WIN 95 UPGRADE

there probably isnt much of one.  thats what I was thinking but before i got to post my browser crashed.

I'm sure with a bunch of pointless tweaks and changes XP could be forced to run on a sub-requirement PC.

Windows XP uses a processor instruction, CMPXCHG8B, that is not found in processors prior to the Pentium I.

you mean like pro?  i didnt learn the earlier ones so much.

I mean the original 1993 Pentium 1. Actually, it was never called a "Pentium One" it was just a Pentium.

By the way, for a while in the 1990s you could buy Pentium Overdrive cpus that fitted in a 486 socket, and these did have the CMPXCHG8B instruction, so you could install XP on a system with one of these, provided you could get enough RAM installed.

So I was right originally 

I was pretty sure it was a missing instruction.


And of course- a 486 with a pentium overdrive isn't a 486 anymore, since the overdrive chip disables the main CPU and takes over- so the system would be a pentium machine, for all intents and purposes. (probably with a sub-par motherboard, though)

Hey, we don't talk about your motherboard!

But any ways, I don't think it would be worth it to install XP on such an old rig, would be soooo slow.

I mean if a mother board is designed for Win98, would you install Vista on it(just say it was possible)?

Thank you very much!

Your mom sheild also?

Sorry still in Spanish I

It is still a 486.  I dont know how you think that else....  you can have a pent a or celeron and it be a 370 the difference is clock speed.  Fiesta in pantalonis.

sigh.


some 486 computer have a "pentium overdrive" CPU slot.

when you put the PENTIUM processor in that slot, the 486 processor is DISABLED. the 486 processor is NO LONGER USED AT ALL. the main processor is a PENTIUM.

any incongruities there?

Ironic that we've entered the grey area of actually proving the point of someone who's point was refuted to begin with...that a 486 will not accept an XP install...
Anyhow...carry on.

not really, the original post:

xp well run on an 95 comp, i've run it on an old 486 and a p1 so if its at leest a p2 then no problem,(runs just as good a 98 on a p2)
the problem comes with hdd space you need at lest 3 gig of hdd
1 gig to load xp
1 gig to hold all the windows fixes
and 1 gig for all the other apps needed to run it

here it says they ran it on a 486. complete lie.

It's a joke:

Somebody else wrote "Hey, we don't talk about your motherboard!" In Hispanic cultures people, especially teenagers, often trade insults about each other's mothers. A "placa madre" is a motherboard in Spanish. "Y tu mama también" is a teen expression common in Mexico which means "and your mama also". It is also the title of a well known Mexican film starring Gael Garcia Bernal. I combined the 2 phrases.
